How long are you contagious after last episode of vomiting from flu?



How long are you contagious after last episode of vomiting from flu?

If you are talking about the stomach flu (which it utterly unrelated to influenza, so PLEASE learn to specify), that is caused by norovirus.

Norovirus is EXTREMELY contagious and hardy. If you have recovered from symptoms, you can still continue to shed virus up to a WEEK afterwards.

Make sure you and your 3 kids (plus dad if he's there, too) wash your hands often with hot, soapy water. Children are walking germ bombs and are notorious for spreading norovirus. But if you are the primary foodhandler in your house, you need to careful, too. Norovirus can get on food and get spread around. Also, clean your bathroom with a bleach solution (I prefer Clorox cleaning spray with bleach) because the virus gets spread in shared bathrooms because virus particles from vomit-spew can linger in the air.

Also, because this is a VIRAL infection, it's useless to take antibiotics. Source(s): I do norovirus control for your friendly local health department.
i think three days
If you have antibiotics, then it will take a couple of days for the antibiotics to work, but if you are just waiting, you may not want to be near people who are not infected with the flu until the major symptoms go away. id say al least 5 days.
Generally speaking,as long as you are running a fever you are contagious.
Vomiting is only a symptom and just because you have vomitted for the "last" time,doesn't mean you aren't contagious.
Now a days there are different kinds of flu and depending on what organism caused the flu will also be a determining factor as to how long you are contagious.
Some organism are what they call air borne which means that virus can live just as well thriving on the air as they can thriving in your body and can be passed through the air verses contact so the kind of virus you are harboring will determine just how long you will be contagious.
I see that you are "mother of 3" so I would suspect that this epidemic of flu probably hasn't run it's course in your home. . . Good Luck.
I Personally Think One is Not Terribly Contagious (Depends On What Sees as "Terribly") 24 Hrs. After Onset of Immune Response to the Virus, Vomiting is an Immune Response. BTW, Antibiotics Will Have No Effect On the Virus.
